摘要
为了解决远程设备数据处理不及时的问题,提出了一种基于RTX实时操作系统的设备数据处理系统.该系统由RTX实时数据处理进程和人机交互进程两部分组成,其中RTX实时数据处理进程负责接收远程设备端的数据并进行实时的处理,将处理过的数据经共享内存和同步事件对象等通信方式,传输到Win32的人机交互进程进行显示和存储数据,同时用户可以通过控制指令修改远程设备的状态.实验证明,该系统解决了设备数据处理不及时的问题,保证了设备管控的实时性和稳定性,能够满足对远程设备进行实时管控的要求.
In order to ensure the real-time data processing of remote device, a real-time processing system based on RTX is proposed, which is composed of RTX real-time process and man-machine interaction. The RTX real-time process gets data from remote device and processes the real-time data. Then, it displays and storages data by transferring the processed data to a Win32 user interface layer by sharing memory and synchronizing event object. Simultaneously, the user could alter remote device upon commands from man-machine interaction. Experiments have shown that the system can reduce the latency of data processing, ensure the real-time and stability of equipment control, and satisfy the real-time control requirements for remote device.
